and their solutions when trying to create a respectful, open environment for all their children and families. children like to feel good about themselves. they enjoy the feeling of not only knowing who they are but also that others appreciate them, respect them, and value their participation in and contribution to the group. children know differences between people's skin color and gender at a very early age... man: ok, guys. child: hey, des. second child: hey, des. third child: hi. he's got his sister. you're his sister. hendrick: which is why it's so important to begin a program of cross-cultural, non-sexist education as early as possible. woman: what we're going to do is... hendrick: our message is a simple one-- that being different, whether in sex, race, culture, or ability, does not mean inferior. or everything was blue. not like that. you said you wanted that shirt. now, wear it. woman: doina, ian gets to decide what he wants to wear, just like you picked that pretty white dress for wearing. hendrick: our challenge in this program is to learn how to teach the principle of equity-- that, while w

. and in that environment, you have then the ejection of alpha, beta and gamma particles. so it's almost simple geometry. right now, this particle we'd call an alpha particle. this is a helium nucleus. and i'll write that helium nucleus like this. and i'll put a two down here and a four here. and this nomenclature, i hope you're familiar with. this is simply the atomic number. it tells you it's atomic number two in the periodic table of substances, yeah? it's got two positive charges. and the four refers to the atomic mass unit. and that's the number of nucleons altogether. i call this, by the way, nucleons. i can call you a people, a person, but a person can be a male or female. nucleon can be a proton or neutron. see what i'm saying? but there's four nucleons altogether, so it has a mass of four and atomic number two. so that would be the configuration. if i put another proton in there, then it would now be-- does anyone know? it would be the element lithium because now it would have three and up here would be five. and any nucleus that has three protons, by definition and by chemical properties, will

into an environment of heavy balls or light balls? heavy balls. and you want the thing to slow down. let me ask you this. if i take a ball and i throw it against a brick wall-- [makes sounds] --when it bounces off, will it bounce off a lot slower or about the same? about the same. about the same. if i take a golf ball and i throw it against a bowling ball, is that bowling ball gonna slow the golf ball down? no, it's not. so what you do is you take the golf ball and you throw into an arena of ping-pong balls. and if you do that, it will give what? give the energy to ping-pong ball and it itself will slow down. and so what do you do is you take these things and you bounce them off atoms like the size of carbon. did you ever hear about the heavy water? you bounce them off light atoms or molecules and these things will slow down, so they're moderated and will cause the reaction of more of this fission. you call--nuclear fission, gang, breaking apart, nuclear fission, and you will fission more atoms. anyway, this is something that cause an awful lot of excitement. because along with these two, it turns

appealed to him, and they didn't now. finding neither subjects nor an artistic environment that suited him, he left london and traveled 275 miles to the north. he settled in the small fishing village of cullercoats on the north sea and rented a studio two houses from the rescue station, overlooking the beach. here was his first encounter with the wild and elemental forces of nature. the rhythm of life in cullercoats was termined by the fishing boats, which set out at dusk and returned in the morning. gradually, homer began to replace descriptive detail with the concentrated drama of individuals bent on the task of survival in a rugged environment. although he had intended to stay in cullercoats only for the summer, he remained almost two years. in october, he watched the life brigade rescue the crew of a wrecked ship-- the iron crown. he sketched the scene from the beach and later painted one of his largest and most ambitious watercolors. at cullercoats, homer's works took on a new monumentality. in the lives of the fisherwomen, he perceived both the gravity of the human condition and the

, or the environment or national defense, or... whatever. we have to go through those choices. we can't have everything we want. that's an issue that will be an issue for employees and employers. how much of your take-home pay-- what could be your take-home pay-- do you want going into medical premiums? and if you really want to put a cap on it, recognize that that will mean some things-- which are of benefit, but more marginal benefit than other things-- won't be available. the question is can we make such decisions and stick to them? alex capron: i think we could get to the point where we face those decisions and make the kinds of decisions which seem justified enough that they can stand up to those difficult cases. they won't collapse the first time a child with an appealing face doesn't get some treatment that would be lovely if he could get, because it's ranked low enough in our value system, given what benefit the child would get, that it's not going to be made available, and not have that front-page story tear at our heart strings and say, sure, give the child the treatment, because once we do t
